Application filed October 10, 1927. Serial in. 225,359.

The invention relates to window regulator mechanisms and more particularly refers to window regulator clutches. The invention has for one of its objects to so construct the mechanism that the driving and driven members of the clutch are interchangeable, thereby reducing the cost of manufacture and assembly. The invention has for another object to construct the mechanism to provide an extended bearing for the driven member. With these and other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings v Figure 1 is an inside elevation, partly broken away, of a portion of a motor vehicle door having applied thereto a window regulator mechanism embodying my invention;

Figures 2 and 3 are enlarged cross sections respectively on the lines 22 and 3-3 of Figure 1;

Figures 4 and 5 are cross sections respectively on the lines 4-4 and 55 of Figure 2.

The window regulator illustrated in the present instance has the mounting plate 1 which is secured to and depends from the lock board 2 of the door. 3 is the lifter arm of the window reg'ulator rigidly secured to the gear segment 4, which latter is pivotally mounted at 5 upon the mounting plate. 6 is' the pinion meshing with the gear segment and 7 is the handle for actuating the pinion,

which, through the gear segment and lifter arm, raises and lowers the window.

To look the lifter arm in itsvarious positions of angular adjustment when driving force is no longer applied through the handle and also to provide for releasing the look when driving force is applied through the handle, the following clutch is provided. 8 is a cup having the annular flange 9'at its outer end andthe annular flange 10 at its inner end, which latter flange terminates in the cylindrical flange 11. The cup is inserted through the mounting plate from its outer side and the annular flange 9 of the cup abuts the outer face of the recessed portion of the mounting plate surrounding the opening through which the cup extends. 12 is a cupped plate having its web '13 offset outwardly from the plane of the mounting plate and the annular flange 14, which abuts the annular flange 9, these two flanges being rigidly secured to each other and to the mounting plate as by means ofthefrivets 15 Ti lie cup and the cupped plate together form the support and housing for the clutch, the gear a segment 4 extending between the lower portion of the web 13 of the cupped plate and the mounting plate 1. I

(ill

16 is the driving shaft,to the inner endof which is secured the handle 7. This driving shaft has the enlarged cylindrical portion 17 I which is journaled in: the cylindrical flange 11 of the cup and the, reduced outer end portion 18,7which is arranged within the cup. 19 IS the drivlng member arranged wlthin the This driving: member is. preferably:

driving member against the shoulders 22 formed by flatting the opposite sides. The

' driving member has the pair, of diametrically opposite or symmetrically arranged trans versely extending fingers 23. 24 is the driven member. arranged within the cup 8 and formed in exactly the same manner as the driving member 19, this driven member being stamped from sheet metal to cup shape and having the pair of diametrically opposite or symmetrically arranged fingers 25, which are adapted to alternately engage in either space between the fingers 23. "Both sets of fingers 23 and 25 are offset radially inward from. the periphery of the webs of the driving and driven members to accommodate the coil.

spring 26, which encircles these fingers and V is limited in .its axial movement in either direct-ion by the peripheral portions of the webs. This coil spring is adapted to be ex-' panded against the'cup 8 to lockthe clutch from turning and has the inturned ends 27 which extend through the spaces between one of the tongues 23 andthe two tongues 25., j

the arrangement being such that upon'turning the driving member 19 through the handle 7, the tongue 23 of this driving member embraced by the inturned ends 27 engages one of these. inturned ends'to contract the coil spring, thereby releasing the look, after which it, through this inturned end and. the adjacent v tongue 25 of-the drivenmember, turns the driven member. However, if driving force is applied through the driven member one of its tongues engagesthe adjacent inturned end of the coil spring to expand the same. firmly against the cup to thereby lock the through one member and to permit turning parts from rotation.

28 is a pin fixedly secured to the web 13 of the cupped plate 12 as by being riveted thereto and extending axially into the driving shaft 16, the outer end of this pin terminating opposite the cylindrical flange 11. 29 is a bushing journaled upon the outer end of the pin adjacent the web 13 and having fixedly securedthereto the pinion 6 and the driven member 24, this bushing, as shown particularly in Figure 4, having its opposite sides flatted at 30 and the openings in the pin on and web of the driven member being correspondingly shaped. Fins 31 are sheared up from the outer end of the bushing to cooperate with the shoulders 32 upon the inner end of the bushing formed by fiattingthe latter,

- these fins. and shoulders holding the pinion and driven member from axial movement relative to the bushing. The size and shape of the bushing is exactly the same as the size and shape of the inner end of the enlarged cylindrical portion 17 of the driving shaft'so that the driven member 24 may be and is exactly the same as the driving member 19. This bushing, furthermore, forms an extended bearing for the driven member.

From the above description it will be read- I ily' seen that I have provided an improved members operating upon said friction mem-.

window regulatormechanism in which the driving and driven members of the clutch are exactly the same and therefore interchangeable. As a result, theseparts may be manufactured and assembled at lower cost than if they were different. It will also be seen that the clutch is of rigid construction.

What I claim as my invention is:

1.,In a window regulator mechanism, the combination with a stationary member, and a friction member, engageable with said stationary member, of interchangeable rotary driving and. driven members operating upon said friction member to effect locking when driving effort is exerted through one member and to permit turning when driving eifort is exerted through the. other member.

2. In a window regulator mechanism,'the combination with a stationary housing and a friction member within said housingand arranged to be expanded thereagainst, of interchangeable rotary driving and driven her to effect locking when driving effort is exerted through one member and to permit turning when driving. effort is exerted through the other member. g

3.111 awindow regulator mechanism, the combination with' a support, of a driving member journaled upon said support, a pin upon said support and a driven member upon said pin, said driving and driven members being interchangeable and operating to effect locking when driving effort is exerted when driving other member.

4. In a window regulator mechanism, the combination with'a support including a cup, of a driving member journaled in said cup, a pin upon said support, a driven member effort is exerted through the journaled upon said pin and a coil spring within said cup and arranged to be expanded thereagainst, said driving and driven mem bers being interchangeable and operating upon said COll spring to effect locking when driving effort is exerted tlii'o'ugli'oiie mem ber and to permit turning when driving effort is exerted through the other member,

5. 'In a window regulator mechanism, the
